The mother of a 13-year-old boy who suffers from a rare form of alopecia has criticised his school after it banned him from wearing a baseball cap. Dale Platts, from Newark in Nottinghamshire, was told he could not wear his cap to Robert Pattinson School because it broke its dress code, even though it protected his bald head and eyes. Stuart MacFarlane, headteacher, would not comment on the case.
